IIRC, your game status when getting a kill must be undetected.Originally Posted by jkg1708 Go to original post
I recall earlier posts on this subject that the actual counter also might not be accurate, for example Panther class.
Here's what I would try. Go to a well populated base. Plant c-4 on the ground or a vehicle to get a secondary explosion. Get a good hiding spot far away from the vehicle, but still nearby the base. Trigger the C-4 and monitor enemy movement. Once they are investigating the explosion, hopefully clustered, use the class's Azrael missile attacks. If you run out of targets or Azreal radio devices, bug out without being detected, restock devices either at Erewhon or a bivouac (depending on your gameplay settings) and go to an enemy location and repeat.
I actually completed this by just roaming around going from cache to cache looking for the AUG Scout which I still havent found. See an enemy, shoot, repeat. Being suppressed and concealed helps but not necessary.. As long as youre not spotted. They can be on alert/searching but as long as the spotting indicators dont turn red youre fine. good luck!
I finished it, but I was detected in between. So I think it's just 30 in total, not necessarily consecutively.
I'm not entirely sure what happened anyway. I started the game the next day, and the first undetected kill finished the challenge.
Maybe the counter was at 29 the day before, maybe it was a bug, I don't know.
